Abstract

Appareil de chauffage pouvant être installé autour d'une canalisation de fluide dans un dispositif d'injection et comprenant les éléments suivants : un tube interne contenant un premier matériau conducteur de chaleur ayant un coefficient d'expansion donné. Ce tube interne d'une dimension longitudinale donnée comprend une surface interne et une surface externe. Le montage comprend une première bague dont la surface interne recouvre la surface externe du tube interne sur une courte distance à un endroit particulier du tube dans le sens longitudinal. Cette première bague contient un second matériau dont le coefficient d'expansion thermique est plus faible que le premier coefficient. L'appareil est muni d'un dispositif de chauffage qui chauffe le tube interne jusqu'à une température prédéterminée.
